Warrington Wolves carry one of rugby league's longer histories, and green and white has been part of their visual identity for generations. This 2013 away shirt, made by Isca, brings the horizontal hoops into an alternate context, a quieter counterpoint to the club's more familiar primaries. Isca occupied a niche but genuine place in British rugby league kit during this era, and this piece captures both the brand and the club at a particular moment. For a collector, it's a document as much as a garment.
